My first thought - it looks... normal. Seriously, what's with these 3d games, they all seem to look like clones of clones. No matter if it's Diablo 3, StarCraft 2 or this one - we all seen it before.
I hope I'm wrong...

Depends on how much and how long each episode is in terms of hours of single player gaming. Also what the rewards are (in gaming terms) for completing a particular episode and replaying it looking for secrets and bonuses.

Nothing in Team17's history leads me to believe that they can see the true potential of a regular episodic game release other than the $$$.

Nor can I see them able to avoid the pitfalls associated which such a game and come up with a workable, value-for money, rewarding game.
